The number of items that can be processed will be different according
to the time interval that inquires about data at Human Machine Interface.
LonWorks Gateway can process 20 items of Acknowledged Service Type per
a second. Therefore, the amount of data that can be processed is decided
according to how frequently HMI inquires about the data and the number of
indoor units that can be connected is decided by this amount of data.
* For example : In the case that HMI inquires about the 27 items of
Acknowledged Service Type by an indoor unit.
When HMI inquires for data at 30 seconds interval, 22 indoor
units can be connected, at 60 seconds interval 44 indoor units
can be connected, at 120 seconds interval 88 indoor units can be
connected.
The renewal cycle can be different according to the provided NV.
